In this paper we have presented the results of a simultaneous Monte Carlo analysis of PDFs and FFs constrained by a diverse array of data from inclusive and semi-inclusive DIS, Drell-Yan lepton-pair production, and SIA in \(e^+ e^-\)  collisions.
The analysis extends the previous JAM19 [1]} simultaneous fit by including in addition unidentified charged hadrons in the final states of SIDIS and SIA, and increasing the flexibility of the PDF and FF parametrizations.
